Application filed February 17, 1920. Serial No. 359,252.

.have invented certain. new and useful lmprovements in StorageBatteries, of which the following is a specification.

My invention relates to storage batteries i and particularly to meansfor supporting separators which are placed between the positive andnegative plates in the battery.

it has been customary heretofore to support the separators by allowingtheir lower edge to rest upon ribs or projections in the Abottom of thebattery cell.

This means o'l' supporting'the separator has the disadvantage that theseparators worlr down on account of the movement of the elements 1n .thejar and the friction of the separators being drawn across the top of thesupports. The

provision of the supports also complicates the bottom of the jar orcontainer and interferes with the removal oi sediment which inevitablyaccumulates in the bottom of the cell.

, My invention has the advantage of eliminating the ribs in the bottomof the jar, thus making it easier to remove sediment and the furtheradvantage that thesev separators form, with the other parts of thebattery, a'unit with which the separators are removed when it isnecessary to so remove'the plates for repair or other reasons.

My invention is shown in the attached 'drawing which accompanies thisspecification and forms a part thereof.

In the drawingr is shown a sectional view of a battery with certainparts broken away to show their relation to each other.

The battery comprises a jar or container l of hard rubber or othersuitable material' provided with a cover 2, which is sealed by suitablecompound 3 after beingl placed on the The jar is oii'set at -l so as totorni a ledge upon which rests a plate holder' 5. One end oiE each platerests at a point (i and the other end at a higher point T on theopposite side of thecell and each oi' the plate holders 5 has a seriesof supporting points at the level of the point and also a series ot' sup)ortingv pointsut the level ot' the point 7. i iter the plates aroplaced iu position, as shown, an insulating strip H is passed throughtransversely the plates and engaging the nected to a. terminal 10 in theusual way and each of the plates ot' the opposite polarity is connectedto the terminal ll. These terminals pass through openings in the cover 2and are fastened to Vthe cover by means of nuts l2, which are screwed,on to the terminals and by reason of which flange 13 is drawn upwardlyagainst the cover and held and connected therewith through washers 14,15 and 16. Suitable filling and ventilating means are provided in thecenter of the cover which means need not be described as thy do not forma part of my invention.

laced between each positive and negative plate is a separator composedof a perforated rubber Sheet 18 and an unperforated wood or other sheet19. In the upper part of rubber sheet 18 are two openings 20 and 21,through which rods 22 and 23, respectively, pass. These rods are ofinsulated material and rest upon the upper edge of the plates andthereby supporting the rubber sheets 18 from the top o1e the plates. Thelower part of each sheet 18 is also provided with two openings 24. and25, through which pass rods 26 and 27, respectively, which are also ofinsulated material. bese rods, like the rods 22 and`23, extendtransversely' in the. late across the cell and the lower edge o the woodsheets 19 rests upon these rods 26 and 27 by which they are supported.

l `iom-the form it will be seen that the composite separat/cris carriedby the plates through the rods 22 and 23 and 26 and 27, and by reason ofthis construction, the plates and the separators constitute a unit whichwhen locked in place by the members 8 can readily be removed from thejar by liftin oii the cover 2. By this construction, it wi l be notedalso that there are no obstructions in the bottom of the jar, therefore,more this construction the unit may bev easily and readily removed andthe jar readily cleaned of sediment.

Having described my invention, what IY l members 2. In a storage batteryof the usual type, having positive and negative plates alter` natelyarranged and separators between adjacent plates one composed ot afibrous material and another of non-fibrous material, the combination ofmeans for supporting separators in place comprising means for supportingthe non-fibrous members from the plates and means carried by thenonfibrousmembers for supportingr the fibrous member:

.3. In a storage battery ot the usual type, having positive and negativeplates alternately Iarranged and separators between adjacent plates onecomposed of a fibrous material and another of non-fibrous material, thecombination of means for supporting separators in place comprising anyplurality of rods resting on top of plates and extending throughopenings in the nonfibrous members and rods extending through openingsin the bottom of the non-fibrous members 'upon which rods the fibrousmembers rest, whereby a larger space is rovided in the bottom ot' thebattery jar tor sediment and the same is more readily removable.

4. ln a storage battery or the usual type, having positive and negativeplates alternately arranged and separators between adjacent plates onecomposed ot' a fibrous maname to this specification.
